New study shows November-to-March precipitation (when rainy season peaks over most of the Southern Hemisphere land mass) was significantly reduced both in the Southern Hemisphere tropics and subtropics due to a weakening of the subtropical convergence zones during the mid-Pliocene Warm Period.

Research brief: How land and ocean characteristics impact wintertime stationary waves.

This study looks at the average climate in the northern hemisphere with a simplified climate model. It considers the atmospheric effects of mountain ranges (Tibet, Rockies), contrasts between land and ocean surface, and ocean currents at the surface (such as the Gulf Stream) and their impact on winter climate.
